The medieval mind was always fertile in experiment. It had all the freshness of a new age that was ceaselessly driven by new circumstances to adapt the fashions of Christendom to conditions violently alien. The restless constitution-making in England, the long experiment in liberty that marks the line of Plantagenet, is part of the same effort; and it is no less visible in the disorderly histories of Florence and Venice. The Cathedrals are one expression of it, the Guilds another, and the Crusades flung valiantly abroad the same temper of adventure, the same daring that would risk defeat or even face certain failure.
As the central force of Christendom the Papacy was peculiarly subject to the same romantic influence, as the stories of Hildebrand and of Innocent III abundantly prove. John XXII with his curious career as theologian, as politician, as apostle, is another instance. The greatest foreign missioner of the line of Pontiffs since the days of Peter, he bears witness in the magnificence of his ideals and his unconquerable hopefulness to the same indomitable spirit. To his hand the Orders of Friars, particularly the Dominicans and the Franciscans, were the most fitted and best used instruments. It will be sufficient to quote the opening words of his Bull of 1318 to the Dominican Order, to show how tremendously alive the Church had become, both in head and members, to the need of Catholic propaganda. The Bull is addressed to “our beloved sons, the Friar Preachers in the lands of the Saracens, Pagans, Greeks, Bulgars, Tartars, Alani, Gazaenes, Goths, Ruthenians, Jacobites, Nubians, Nestorians, Georgians, Armenians, Indians, Macolites, and other unbelieving nations in the East and North.”
